C1

The record on your building is public. Reading it is the hard part.

KOANO reads the violations, the ownership, the permits, and the risk data tied to an address, whether you own the place or rent it, and tells you what it means.

Not a tool for gentrification.

Know what's happening to your property's value before your neighbors do, and know what to do about it.

For homeowners, renters, and neighbors

01What you get

What this reads today

Violation history

Every HPD housing maintenance violation on the building, by class, open or closed, with the trend across the last two years against the two before it. Plus ECB violations by severity and active DOB complaints. HPD violations apply to buildings with three or more units, so a small building returning nothing is a coverage fact, not a clean record.

Who owns it

The registered owner and managing agent from HPD records, the other buildings held under the same entity, and the violation volume across that portfolio. Ownership held through separate LLCs per building will undercount, and KOANO says so rather than presenting a portfolio as complete.

What is being built nearby

Approved DOB permits around the address, and what the zoning allows on the lots next to you.

What the ground is doing

FEMA flood exposure, neighborhood demographic change, price movement, crime trend, and whether the tract is a designated Opportunity Zone.

02What is not built yet

What is not built yet

Displacement risk scoring

The inputs are live. The model is not. Building this properly means publishing how it is weighted rather than handing you a number and asking you to trust it, and that is a different piece of work than wiring up a data source.

Affordable housing lottery listings

There is no public feed for open lotteries, income limits, and deadlines. Doing this means scraping Housing Connect, which is fragile enough that it would break quietly. It waits.

Eviction filings and harassment records

Housing court data is not public in the way permit data is. KOANO reads ownership and violation patterns, which is real and useful, and it does not claim to read the court record, because it cannot.
